Search using google to patch ASRock Bios. You may or may not need to use a DSDT. There was no support in Mavericks for the HD 7790 GPU card, but there is some interesting developments that you should perhaps keep an eye on/ask for advice:

You might get this running and to be honest if you see people with similar hardware ASRock or even MSI Z77 chipset and same graphics then they will be able to help with support getting your build running.

Good luck.
